2 Claims.

This i a continuation in part of the application filed June 1, 1936,Serial Number 82,716, issued as Patent Number 2,168,766 on August 8,1939 and of application filed August 7, 1939, Se rial Number 288,880,issued as Patent Number 2,259,806 on October 21, 1941. I

This invention relates to patches adapted to be applied to veneer,plywood panels, or wood boards to fill a cut-out space therein fromwhich a pitchpocket, knot, or other defect in the wood of the panel hasbeen removed.

Many attempts have been made to make a patch suitable for the handpatchers, a patch that would fit perfectly into a previously preparedcut out space from which a knot, pitchpocket or other defect has beenremoved from the wood of the panel, a patch that would fit perfectlyinto a previously prepared cut out space or hole, a patch that wouldleave no hole or glue stain at its ends after insertion into the patchhole, heretofore the patches used in the hand patching method havefitted poorly at their ends, thereby leaving a small hole which caused aglue-stain at the ends of the inserted patch, thus lowering the gradeand salability of the manufactured product, and caused many complaints,extra expense, much loss in time, thus lowering the amount of productionand increasing the cost of the individual panels. Therefore in order toavoid having a hole, or lue-stain at the ends of these inserted patches,I have devised a patch with an improved end or tip, the aforesaid end ortip to be known a a tail or sliver.

The hole which this tail or sliver in my improved patch is designed tofill, at the end of the previously prepared hole, has a number ofcauses, the most troublesome one being, the more or less square edge ofthe patch-hole cutting tool at the end of the cutting edge, required tosustain the edge of the patch-hole cutting tool in its proper form,through which the patch-hole is not brought entirely to a point.Therefore when the old style patch is inserted a hole remains open atthe patch end. Another cause is the tendency of the patch-hole cuttingtool to slip sidewise when struck with a hammer, while preforming thecutting operation.

It is the general object of my invention, to provide a patch with agreatly improved end or ends, by the addition of a projecting tail likesliver (more or less ribbon like in form) at each end of the patch,thereby creating a patch that will fit perfectly into a previouslyprepared patchotherwise have been left open in the finished product,thereby causing glue to ooze out and cause a glue stain, and myinvention eliminates this trouble.

It is the further object of my invention to provide a patch that can berapidly and accurately manufactured in a single operation, therebycutting down the cost of the individual patches and to enhance the valueof the patched piece, also to provide a patch with a beveled edge,whereby it may be forced in tightly.

I attain these and other objects, by the im provements herein describedand illustrated in the accompanying drawing, of which Fig. 1 is a detailperspective view of a patch showing the top or face side.

Fig. 2 is a plan view of the patch shown in Fig. 1, showing the bottomside.

Fig. 3 is a plan view of a section of the patch shown in Fig. 4 in thedirection of the arrows 3-3 of Fig. 4.

Fig. 4 is a top plan view of a patch similar to the patch shown in Fig.1 except that the two slivered portions of the edge curvature extendedare on the same side edge of the patch.

Fig, 5 is a bottom plan view of the patch shown in Fig. 4.

Fig. 6 is a plan view of the top side of a patch similar to the onesshown in Figs. 1 to 5, except that it discloses a different form of sideedge curvature.

Similar numerals of reference refer to similar parts throughout theseveral views.

The patch I shown in Figs. 1 and 2 is formed with two flat oppositeparallel sides, known as the top and the bottom of the patch I, and thispatch I has two similar curved side edges 2 and 3 each having the sameradius and approaching each other at sharp angles and joined to eachother by very short slivered edge portions 4 and 4 with one at each endof the patch I and each split or short slivered edge portion 4 is on theopposite or opposed similar side edge curvatures 2 and 3 as shown inFigs. 1 and 2 with the slivered edge portions 4 and 4 running parallelto the grain of the wood in the patch and thereby forms the two sideedge curvature completing the perimeter of the patch and extending thetip of the patch to form the tail or splinter 5.

In the patch shown in Figs. 3 to 5 the patch 9 is formed with twosimilar curved side edges 6 and 1 the similar curved side 1 being longerthan the similar curved side 6, and both side hole and completely closethe hole that would edges have the same radius, the side edge 6 isextended at both ends by the sliver 8 and 8 to join at both ends theopposite side edge curvature I thereby forming an extended end, thetails or splinters In.

In the patch I I shown in Fig. 6 the same structure is incorporatedtherein as is shown in Figs. 1 to 5, except that it has a difierent formto illustrate the various shapes that might be used.

Thus it will be seen from the foregoing disclosure. that the patch is animprovement over the old patches in use and disclosed in Welchs patentin Figs. 9 and 10, dated Sept. 20, 1932,

as Patent No. 1,878,081, and in Stager, 1,629,595,

dated May 24, 1927, Fig. 15.

It is of course understood that many variations may be made in thedetails of construction of the above described patch, without departingfrom the spirit of my invention as outlined in the appended claims.

Having therefore, described my invention what I claim and desired tosecure by Letters Patent, is:

1. A patch having curved side edges, approaching each other on acuteangles and joining in a sliver projecting from each point of junction.

2. A patch having curved side edges, approaching each other on acuteangles and joining in a split at each point of junction, wherein a smalltail is formed at each end of the patch and wherein one side edge ofsaid tail conforms to the same curvature as the edge of the patch it isthe continuation thereof, and wherein the opposite edge of said tail isformed by a split parallel the grain and connects the two opposite sideedge curvatures of said patch at each point of junction.
